'libsass' bindings not found


I have just installed the latest Ionic CLI, which then told me I needed up update my node runtime. So I went to the node website and downloaded the latest version (v0.12.5).

Now, when I run ionic serve --lab on my app, I get the following error in the command prompt…

ionic $ C:\Users\Matthew\Documents\IonicProjects\bmw\node_modules\gulp-sass\node_modules\node-sass\sass.js:22
  throw new Error('`libsass` bindings not found. Try reinstalling `node-sass`?

Tried running npm install node-sass but didnt fix it. Also tried uninstall then install node-sass and also rebuild node-sass

None of the above work. Anyone know how to sort this out?
